Independent analysis of Chinese Next Generation Commercial Cryptographic (NGCC) algorithms program candidate algorithms. This site is not affiliated with NICCS.

Security — security findings (classification policy), each linking to the full report and its reproduction steps.
Performance — cycle counts for ICCS-facing parameter sets, placeholder-hash shares, relative hash measurements, and detailed pages retaining every measured implementation.
Side-Channel — scoped constant-time source-level notes for all 119 candidates, including cases without a finding.
Harness — the build and test tooling the reproductions rely on.

Citing

To cite this web site:

@misc{ngccdev,
  author       = {Saarinen, Markku-Juhani O.},
  title        = {{ngcc.dev}: Independent Analysis of the {NGCC} Candidates},
  year         = {2026},
  url          = {https://ngcc.dev/},

To cite one finding, use its stable xxx-yy-z identifier and credit the people named in that finding's Credit field, who are often not the maintainer of this site:

@misc{ngccdev-sign-32-1,
  author       = {Vulnerability Author},
  title        = {{UVW}: Every Signature is Accepted},
  year         = {2026},
  url          = {https://ngcc.dev/reports/sign-32.html},
  note         = {Finding \texttt{sign-32-1}, ngcc.dev. Accessed 2026-10-08}
}

The braces around {ngcc.dev} and the acronyms stop BibTeX from lowercasing them. Load hyperref or url to make the link clickable. For biblatex, use @online and give the access date as urldate. The original standard styles (plain, abbrv, alpha, unsrt) ignore the url field; with those, either use a URL-aware style such as splncs04 or IEEEtran, or move the address into howpublished = {\url{...}}.

Findings are added and revised continuously, so please cite the date you read a page rather than the date prefilled above, and quote the finding identifier so the reference stays resolvable if a title is reworded.
